vApplication iedumh 23,1894. serial N0.5o4.863. (umbau.)

To all whom it may concern:

Be` it known that we, JOSEPH YARDLEY JOHNSTON and BRoR F. BEReH,'citzensof the United States, residing at New York, in the county of New Yorkand State of New York, have invented certain new and usefulImprovenients in Embossed-Printing Presses; and we do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

Our invention relates to improvements in presses for embossed printing,and more particularly to improvements in the press covered by LettersPatent of the United States, No. 504,680, issued the 5th day ofSeptember, 1893, to Joseph Yardley Johnston. The basic elements of theJohnston press-the springactuated screw plunger, the revolving die, andthe spring-and-camactuated inker and wiper-are retained, and the presentinvention consists in novel and improved arrangements and constructionsof these fundamental parts and of the mechanism operating them, ashereinafter fully described, with the result of increasing the lspeed ofthe press, diminishing the expense of operating it, and greatlyaugmenting the perfection of its work. We attain these objects by themechanism illustrated in the accompanying drawings, in which-- Figure Iisa front elevation of an embossed printing press embodying 'our saidimprovements.

Figs. XIX and XX show de Similar letters and numerals designate thecorresponding parts in all the figures. v

A is the frame of the press, having the base a, and being. provided withthe arms l, 2, and 3, supporting the driving mechanism. The press frameis mounted upon a suitable stand B, having the cross-tieC, provided withthe flange b, which supports the paper-feeding and wiping device ashereinafter explained.

D is the main shaft, located centrally near the top of the press,andcarrying thegdriving pulley E, loosely mounted thereon, but'withrooout lateral play. The movement of themain shaft is controlled by handle9, in connection with an incline not shown, spring 10, and rod 8, havingthe forked arm 7, whereby the sliding clutch 6 is moved backward andforward into and out of engagement with the fixed clutch 5, attached tothe driving pulley.

G is the revolving die-carrying arm, firmly attached at one end tovertical shaft F, and having at the other end die box 26, in which movesup and down die plunger 25, carrying at its lower end die block 28,which is supported by spring 27.l Motion is transferred from shaftD toshaftF by pinion S, cog-wheel T, supported by stud 16 and carryingmutilated bevel gear t, and bevel pinion Q. The teeth of mutilated bevelgear t cause one complete revolution of pinion Q, and by consequence ofrevolving arm G, at eachrevolution of cog-wheel T, and are so disposedthat the blank portion 14 of the gear is presented to pinion Q while theoperations of locking and unlocking the revolving arm and striking theimpression blow are being performed.

Revolving arm Gis locked and unlocked by locking-pin H, which movesvertically in sleeve 17, attached to arm 2, being pressed downward byspring 18 and elevated by lever I. Lever I is pivotally attached to bush19,

its forward end resting in slot 2O of the lock-l ing-pin, and its rearend, carrying roller 15, resting against cam K, attached to the frontface of cog-wheel T. Fig. X shows the relation of blank space 14 to camK, and the projections 2l and 24 of cam K, by which respectively thelocking pin is raised just be fore the revolving arm brings the dieplunger under the screw plunger, and just after the impression blow hasbeen struck. The lower end of the locking-pin is furnished with fingers22 and 23, the former impinging upon rib g suitably located on the topof the revolving arm and by friction checking it, and the latter finallylocking it without jar as the spring forces the pin down over rib g,which is adapted to fit snugly in the space between the two ngers.

Die block 28 has on its under side a transverse dove-tailed groove 30,and sliding in it the correspondingly dove-tailed tenons 30 of the twojaws 29 and 29. These tenons form suitably threaded nuts for therightandleft hand screw 31, supported by plates 32 and 32', and servingto move the jaws (which hold die d) conjointly in andout from a commoncenter. For centering the die longitudinally is provided the gage 33,having the channel 37 to receive the point of set-screw 36, and whichslides in a suitable groove 31', located centrally in the bottom of thedie block, on one side of and at right angles to groove 30. The bottom34 of the gage is flush with the bottom ofthe die block, but theprojecting shoulder 35 catches the die and thus accurately centers' itlongitudinally. lOn base plate a of the press, and directly beneathscrew plunger 3S,

rests the movable counter plate @,held in' place by dowels or otherwise,upon which the counter or counter die is built up. This movable counterplate, in conjunction with the sliding jaws and gage, admits of theremoval of the counter' and die and their accurate replacement at anytime.

Screw plunger 38 moves up and down for about one-third of a revolution,in a suitable nut located centrally in the front part of the pressframe, its upper. end passing through the casing L, and carryingweighted cross bar R. In the bottom of the casing lies coil spring 40,its inner end being secured to sleeve 41, which is keyed to the plunger,and its outer end resting loosely against lug 42 of ring 43, lyingmovably in the bottom of the casing. The exterior face of ring 43 at thefront of the press is provided with teeth, into which fits, through anopening in the casing, the' thread of worm W, moving in bearings 44 andoperated by the square head 45. At the upper part of sleeve 41, andcarried by it, is arm 57; and pivotally attached to the outer end of arm57 is link 56, having (at its head) shoulders 58 and 59 and roller 55. 4

Superimposed on sleeve 4l, and surrounding screw plunger 38, is hub 47of cog-wheel 5l, located in the upper part of the casing, and revolvedby pinion 50, carried at the top of shaft 48, which is supported inbush49, and driven by bevel wheel X'on its lower end and bevel wheel V onmain shaft D. Cowheel 51 carries a tripping bolt 62, adj'ustably locatedin slot 63, and the depending sleeve 52. Surrounding sleeve 52, and atthe same height above the bottom of the casing as link56, is ring 53,held in place by three pins passing through slots 64 in ,the sleeve, thethird pin being rigidly attached to one end of spring 65, within thesleeve, the other end of spring 65 being rigidly attached to the sleeve.On the exterior surface of ring 53 is the rib or shoe 54, and on theinterior surface of the casing, at about the same height from thebottom, is the fixed shoe 60. Directly in front of pinion 50, and in thetrack of link 56, is the finger or cam 6l, supported by standard 46,rising from the floor of the casing.

In operation, the forward end of elastic shoe 54, carried by sleeve 52of revolving cogwheel 51, catches shoulder 58 of link 56 and therebycarries the link with it, thus turning screw plunger 38 and winding upcoil spring 40, until in its progress link 56 is thrown 0E shoe 54 byfinger 6l, when its shoulder 59 catches upon the forward end of shoe 60,and is there held until tripping bolt 62 comes along and disengagesit;and then coil-spring 40 retracts the screw plunger, and theimpression blow is struck. At the instant of the pluugers rebound, theforward end of shoe 54 again catches shoulder 5S, its elasticitypreventing jar, and the operation as just described is repeated. Thetension of the coilspring, and by consequence the force of theimpression blow, are regulated by worm W and toothed ring 43.

N is the die inker, located in the path of the revolving die,itsreservoir or casing n being supported by shank 102, resting oncoilspring 104, whose heightV is ladj usted by thumb-nut 105, in sleeve103, sustained by bracket O, suitablylattachedy to the base of thepress; whereby the inker is provided with a swivel motion, which adaptsit to any size of die that may be used, and which is regulated byset-screws 107, passing through lug 108, and pressing against bar 106,attached to shank 102. Collecting roller 109 is carried on a shortshaft, which also carries ink agiltator 114, one end of the shaft beingsupported by pointed screw 115, and the other end fitting into a slot inrotating plug 116; whereby the removal and replacement of the roller arefacilitated. The journals `of the shafts of the evener 110 and theinking roller 111 rest in holes located eccentrically in stationaryplugs 113; whereby their pressure on the collecting roller is regulatedand their removal and replacement are facilitated. The agitator androllers are kept in continuous motion in the following manner: Sprocketwheel 4 is secured to driving pulley E, and conveys motion to sprocketwheel 122 on one end of a shaft carried by sleeve 129, which issupported at its center by shank 130, resting on coil spring 131, instandard P, attached to the base of the press frame; at the other end ofthe shaft turning in sleeve 129 is sprocket wheel127, which transfersthe motion by chain 126 to sprocketwheel125, fastened to one end ofshaft 128, turning in sleeve 123, attached to the casing of theinker; atthe other end of shaft 128 is bevel pinion 124, which gears with bevelpinion 117, attached tothe outer end of rotatingplug 116, with the innerend of which the shaft carrying the collecting roller is connected, asabove stated; bevel pinion 117 carries a pin,121, working in slottedlever 120, which is connected by shaft 132 with'forked lever 119,between whose prongs works the pin of crank arm 118, attached to the inkagitator. Near each end of the shaft of the inking roller are the disks112 and 112', upon which the outer ends or cams 39 and 39 of jaws 29 and29 impinge, as the die carrying arm revolves, depressing the inker justbefore the inking roller touches and leaves the die, whereby the edgesof the die are kept clean, and the inking roller is forcibly thrown.

against the face of the die by coil-spring 101.

M is the combined wiper and paper-feeding device, located in the path ofthe revolving die, 'm being the top plate or wiping surface attached byscrew-bolt 86 to plate 68, which is also the top cross-piece and 67 thebottom cross-piece of the frame 66, which car-k ries the paper-feedingapparatus and wiper, and being the lever which supports it all by meansof the ball-shaped pivot 69, downwardly projecting from the center ofcrosspiece 68 into a suitable socket in the lever. The outer end oflever A70 lies between and is attached by pivot 7l to the forked ends 72of an arm projecting from the base of the press,

the die.4 Simultaneously hook 77, which is pivotally attached to theinnerend of lever 70, actuated by spring 79, catches upon plate 78,attached to arm 3, and rmly holds the wiper while the die is passingover it. The length of the wipe is regulated by tappet 80, adj ustablyattached to shaft F, which disengages hook 77 from plate 78; whereuponthe entire frame drops by gravity, its lower end being guided by pivot12, depending from cross-piece 67, and passing through eye 11 in iiangeb of cross-tie C, and being received on rubber spring 13. The wiper andlpaperfeeder being thus combined, and thus elevated and pressedtogether, the wiping paper is kept under a uniform tension, and itseffectiveness thereby greatly increased. And the supporting and guidingpivots 69 and 12 allow a swivel motion lto the frame, which may beregulated by set-screws 136 passing through cross-tie C, and thusprovide a delicate adjustment of the wiping surface to the varyingsizesof the dies in use.

Wiping plate m is secured at its center to cross-piece 68 by screw-bolt86passing up through ball-pivot 69, which is hollow, into the projection85. It is adjustable at four points, and its pressure on the die isregulated, by bolts 82, passing up through ycrosspiece 68 and itsprojecting eyes 81, and pressing against rubber springs 84, resting incups 83, depending from the under side of the plate. Passing throughside bars 89 at either end of the wiping plate m are eccentricallyjournaled roller 87, its eccentric side when turned touching the undersurface of the wiping plate, and

roller 88, slotted along its entire length between the side bars, bywhich rollers is attached and firmly secured the felt or other materialcustomarily covering the wiping plate in the following manner: Roller 87being suiiciently turned inwardly, the end of the felt is passed betweenit and the upper plate, and the roller is'then turned back, catching thefelt as in a vise; the other end of rthe felt is carried over-plate mand passed through the slot in roller 88, which is then turned until theend of the felt lis caught under and secured by the surrounding fabric,and the whole sufficiently stretched, .when roller 88 is fastened by ajam nut. Over the wiping surface thus prepared passes the wiping paperfrom supply roller 90, (removable kby merely turning latches 91,)through' feeding rollers 92 and 93,'to the take-up roller 94.

The paper-feeding operation is thus performed: Attached to the innerside of the vframe 66 by studs, which pass through slots 133, israck-bar 95, having teeth opposite the IOO Irc'

journals of rollers 94 and 92, which engage with the teeth of sectors97, turning loosely on said journals, and carrying pawls 98, which (byaid of springs 137) engage withl'ratchet wheels 99, keyed to the rollershafts. When the die has been wiped and hook 77 thrown off, bevel cam75, pressing upon roller 134, pushes down rack bar 95, whichsimultaneously turns the feeding and take-uprollers. To regulate thequantity of paper fed, ring 100, carrying ange or hood 101is adjustablysecured to the eye forming the bearing of the feed roller journal, andthe location of the hood in respect of the ratchet wheel determineswhich tooth of said ratchet wheel the pawl shall engage with, and byconsequence the extent to which the feed roller, firmly keyed to itsshaft, shall turn. take-up roller runs loosely on its shaft, beingcarried along by friction, regulated by thumb nut 135 to the strength ofthe paper; and while its shaft turns a uniform distance at each downwardmovement of the rack bar, the roller itself turns only enough to take upthe waste paper fed to it. When the pressure of cam 75 is removed, rackbar 95 is retracted by spring 96, until it is in position for an` otherfeed movement.
